The 37-year-old referred to “many interesting opportunities to explore within Toyota Gazoo Racing” in the announcement of his WEC exit, and Toyota insisted he would maintain ties.

While he is yet to confirm his plans for next season, Alonso suggests a return to Formula 1 or a season in IndyCar are possibilities, and believes he’s as race sharp as ever.

“As I said last year when I stopped Formula 1, I feel in the best moment of my career. I’ve never been as quick and as prepared as now,” said Alonso.

“I feel strong and ready for big challenges. It can be Formula 1 in 2020, it can be IndyCar. It can be different series outside all of this.

“If I remain free, in the second part of the year I will have that possibility to decide what I do in 2020. That’s the reason why I couldn’t commit in May.

“I need to wait and see what is going to happen in the next couple of months. Being free of any obligations is the best way I could approach those opportunities. If I was already committed with something, maybe those opportunities would not be there.

“I have two or three ideas on my mind that you will probably know in a couple of months. I am working on those and we will continue this challenge of mastering different ways of motorsport.”

Alonso will be in action this weekend as the World Endurance Championship heads to Spa-Francorchamps for the penultimate round of the 2018/19 season.
